iMPRovl-:M ENT IN LAMPSHADES.

Specication forming part of Letters Patent No. 90,135, dated May 18,1869.

To all whom it may concern.-

Be -it known that I, JAMES E'TRAVIS, of

the city, county, and State of New York, haveV y form part of thisspecification, and in which is represented a vertical section of a shadeconstructed according to my improvement, and

a applied to a gas-burner.

This .invention consists in a translucent disk applied to the bottomofthe shade of a gas or other burner for illuminating purposes, wherebythe rays of light reilected downward from y the sides of' the shade arepartially retracted and mellowed by their passage through the said disk,thereby giving a softer andinore agreeable light.

Referring to the accompanying drawings,

" A is a gallery of ordinary construction, sur

rounding the burnerfor the support of the re! iiecting-shade B. C is thetranslucent disk, constructed of ground glass, mica, or othertranslucent or semi-transparent material, and having a central openingthrough it to allow of its'being passed over the burner. It is made tocorrespond in size and form with the bottom of the shade. It is rstplaced upon the gallery, and the shade placed over it so as to rest uponit, as represented. It may be flat, as represented, or of concavo-convexor inverted conical form.

By means of this inventiona softer an d more uniformly-concentratedlight is obtained than by the ordinary shade.

Ido not claim a shade constructed with a transparent or semi-transparentbottom; but

What I claim as my invention, and desire to have secured by LettersPatent, is The translucent disk C, made of a separate c piece from, butapplied in connection with, the

shade of a gas or other burner, substantially as and for the purposeherein set forth.
